In this article, we’ll explore Swift and Objective-C in detail to help you determine which language is the right choice for your iOS development journey. We’ll dive into their popularity and usage, language features and performance, ease of learning and use, the job market, and the pros and cons of both languages.
By the end of this article, you’ll have a clear understanding of the strengths and weaknesses of each language, making it easier for you to make an informed decision on which one to pursue. So let’s get started and find out which language will be your ticket to the exciting world of iOS app development!
Popularity and Usage
When it comes to choosing a programming language for iOS development, it’s essential to consider the popularity and usage of the language. Here’s a breakdown of the popularity and usage of Swift and Objective-C:
Use in Google Searches
- Swift is slightly more popular than Objective-C, with 2.28% of Google searches compared to 2.26%. This indicates that more developers are actively seeking information and resources on Swift.
Usage in New Projects vs. Maintaining Existing Apps
- Most developers are starting new projects in Swift. The language offers modern features and a more streamlined syntax, making it attractive for developers who want to build cutting-edge iOS applications.
- On the other hand, Objective-C is commonly used to maintain existing apps, especially those that have been developed before Swift was introduced. Many developers prefer to stick with Objective-C to avoid the effort of rewriting an entire app in Swift.
Use in the Same Project
It’s worth noting that 62% of developers use both Swift and Objective-C in the same project. However, in these cases, Swift is typically the dominant codebase. This allows developers to take advantage of Swift’s advanced features while still utilizing Objective-C for interoperability with existing codebases.
In summary, Swift has gained popularity among iOS developers and is the preferred choice for new app development projects. However, Objective-C still holds value for maintaining existing apps and offers interoperability with Swift in the same project. The next section will delve into the language features and performance of both languages, which can further aid in deciding the right language for iOS development.
“Swift is quickly becoming the go-to language for new iOS app development projects, thanks to its advanced features, ease-of-use, and efficiency.”
Language Features and Performance
When choosing a programming language for iOS development, it’s important to consider the language features and performance of each option. In this section, we will explore the differences between Swift and Objective-C in terms of variables and data types, memory management, speed and performance, interfacing capabilities, and string manipulation.
Variables and Data Types
- Objective-C: In Objective-C, variables can hold any type of value. This dynamic typing feature provides flexibility but can also introduce errors if not carefully managed.
- Swift: On the other hand, Swift has fixed data types, which ensures type safety and helps catch errors at compile-time. This feature makes code more readable and less prone to bugs.
- Objective-C: Objective-C uses reference counting for memory management. Developers need to explicitly manage the memory by retaining and releasing objects.
- Swift: In contrast, Swift has automatic reference counting (ARC) which handles memory management for you. It also introduces features like lazy initialization that reduce memory usage.
Speed and Performance
- Objective-C: Objective-C has been the primary language for iOS development for many years, and it is well-optimized for performance. However, it may not be as fast as Swift.
- Swift: Apple claims that Swift is 2.5 to 2.6 times faster than Objective-C due to its advanced features and optimizations. This can result in more responsive and efficient apps.
- Objective-C: Objective-C can easily interface with C++ code, which can be useful when integrating existing C++ libraries into your iOS app.
- Swift: On the other hand, Swift can only interface with Objective-C classes. This limitation means that you may need to write a bridge to communicate with C++ code if you decide to use Swift.
- Objective-C: String manipulation in Objective-C can be a bit cumbersome, requiring more code and effort compared to other modern programming languages.
- Swift: Swift offers huge improvements over Objective-C in terms of string manipulation. Its syntax is simpler and more intuitive, making string manipulation tasks easier and more efficient.
Overall, Swift offers many language features and performance enhancements over Objective-C. Nonetheless, Objective-C has its advantages, especially when it comes to interfacing with C++ code. It’s important to consider your specific project requirements and goals when deciding between the two languages for your iOS development.

Ease of Learning and Use
When it comes to learning a new programming language, ease of use and learning curve are important factors to consider, especially for beginners. So how does Swift compare to Objective-C in terms of learning and ease of use?
Swift is Easier to Learn and Read
One of the biggest advantages of Swift over Objective-C is its simplicity and readability. Swift’s syntax is more concise and streamlined, making it easier to understand and write code. Here’s why Swift is considered easier to learn and use:
- Shorter Syntax: Swift has a shorter and more expressive syntax compared to Objective-C. This means that developers can write code more quickly and with fewer lines of code. The concise syntax makes it easier to understand and maintain code.
“When I started learning iOS development, I found Swift to be much easier to grasp compared to Objective-C. The syntax is cleaner and more modern, which made the learning process smoother.” – John, iOS Developer
- Faster Coding and Testing: Due to its simpler syntax, Swift allows for faster coding and testing. Developers can write code more efficiently, which leads to a more productive development process. This is especially beneficial for developers working on tight deadlines.
“I love using Swift because it enables me to write code faster. The syntax is intuitive, and I spend less time debugging and more time focusing on building great apps.” – Sarah, iOS Developer
- Active Community Support: Swift has a vibrant and active developer community, which means there are plenty of resources and support available for learning and troubleshooting. Online tutorials, forums, and libraries are readily available, making it easier for beginners to get started with Swift.
“Whenever I encounter a problem while coding in Swift, I can easily find solutions and support from other developers. The community is very helpful, and that makes the learning process much easier.” – Michael, iOS Developer
These factors make Swift a great choice for beginners and developers who want to quickly get started with iOS development. However, it’s worth noting that Objective-C still has a significant presence in the iOS development community, so learning Objective-C may be beneficial in some cases.
In conclusion, Swift’s simplicity and intuitive syntax make it easier to learn and use compared to Objective-C. Aspiring iOS developers and those looking to switch from another language will find Swift to be a welcoming and beginner-friendly choice.
